KNX AQS-B-UP (discontinued item)

KNX CO2 Sensor with Display and Buttons

The Air Quality Sensor KNX AQS-B-UP measures the CO2 concentration in the room. The sensor can receive an external CO2 value via the bus and process it with the own data to an overall value (mixed value, e. g. room average).

The KNX AQS-B-UP offers two push buttons that can be used as free programmable bus push buttons.
The KNX AQS-B-UP provides four switching outputs with adjustable threshold values. The switching outputs and further communication objects can be linked by AND and OR logic gates. Additionally, an integrated actuating variable comparator can compare and output values that are received via communication objects.
An integrated PI controllers allows for control of ventilation depending on CO2 concentration.

The integrated display shows the own values and data received from the bus (e. g. date, time). The housing is completed with a frame of the switching series installed in the building and thus merges with the interior.
